Letters Patent No. 85,185, dated December 22, 1868.

IMPRovED.. GAS-MACHINE.

The Schedule referred to in these .Ihettersl Patent and making part o f ythe same.'

To all whom -it 4may concern Be it known that' I, JAcoBD. SrANG, of Dayton, in

' the county of Montgomery, and State of Ohio, have -invented a new andimproved'Gas-Machinefand I d o hereby declare that the following. is a full, clear, and

. .exact description of the construction and operation of the same, reference being had to the annexed drawin making apart of this specification, in which-- Figure -1 is a side elevation. l

Figure 2,-is a top 'viene The. object ofthis invention is to so improve the process of making illnminatingegas or vapor from naphtha', gasoline, and other hydrocarbons, that a better gas Qanheproduced in'largel; quantities, and at less expense than heretofore, and the` same machine can. be employed, at pleasure either, for the manufacture of gas'directly from the-hydrocarbon, or for the carburetting Aof common' atmospheric air, as maybe desired.

In can'ying this purpose into effect, I haue con structed and employed, withthe most completesuccess, an improved apparatus, which forms the' subjectmatter of this application, and which I will now proceed to explain. in detail,'making reference, for the- 'purposes of description, to the'drawings above'refe'rred to, in which- A represents the vessel, in which is containedtlle gasoline or other hydrocarbon, from 'which the gas is.

to'be made, abeing ain-nucl', provided with a stopjcock, through which thematerialis vintriulucc-d into the vessel, and

being a pipe, provided with astop-cock, b, through .which s o much of such material `as is required for thepurpose of making gasat any time is fed' from the A4vessell tothe apparatus, Which vaporizes it and `fixes the gas..

After passing from the vessel A, the pipe B is coiled backand forth a great many times upon av low, iiat frame, C, overa shallow vessel, D, so th'at a great ex tent of thepipe will be subjected to the iniiuence of hot air rising from the vessel D'. -The pipe then extends -toa gasolneter; E, with which it communicates,'after which it extendsv bach to the centre of the vesselD, directly under the coils and involutions formed by itself above the vessel, and is 'there `pro'ifided With one or more suitable burners, F.

Stop-cocks b b2 are provided on each side of its '0611-' nection with the gasonieter, in orderto regulate and control the actionof the gas.

The gasometer is of the forni which iscomnlonl y to be seen in large establishments for the manufacture of illuminating-gas, having a water-sealed gas-cylinder, e, rising and falling in a water-cylinder, c', by the pressure of the gas, and guided and supported by a frame, G.

It is also provided with a cord, h, pulleys'h' h', and a crank, H, by which the gas-cylinder can be raised or lowered at pleasure, and with a stop-cock, i, by which gasor air can be allowed to escape, or waterl can be supplied, as circumstances may require.

A I is a pipe, by which the gas is taken from the reservoir E to be used.

Ilnmediatelyatter passing freni the gasometenit' branches off tori'ghtand left, one branch, J,te1-I'ninat ing near by in a1mrner, K,.b i which the quality of the gas may at anytime be tested before it can enter the pipes where it is to be used.

When thus testing the gas, other branch is to he closed.

'When not testing the gas, the stop-cocky" of the' branch JA is to be closed, and the stop-cocky' opened.

'The gas then flows along through pipe I in to a horizontal senli-cylilulrical vessel, L, Where it may be subthe stop-cock j -of the jected to a bath, forjthe purpose of purifying'it, o1' to the action of .anys11bstances,ii)r the purpose of enriching it, or otherwise varying itsquality.

'After leaving the vessel L, it passes through another similar vessel, M. It ,is then conducted to the second gasometer or res. ervoir N, from which a-.pipe, O, 'carries it to the burners'o, where it is to be consumed.

Byeniploying; the two vessels L and M, the quality 'of thegas' can be changed and controlled to .any te,

quired degree, one o i' thenrbeing used to purifyiit,

and the vother to vary its quality, by enriching itor both may be used. for pnrifyingit, if desired.

Each vessel is provided with a cock or funnel, l m,-

by which the substances employed in it may be readily introduced or re'noved,

After leaving the vessel M,'the pipe I connects with a side-pipe, l), leading `from an air-pump, Q, by means of :which the gas can be diluted to any required extentbeforepassingI into the reservoir whence it is' to be taken for use.

Suitable 'stop-cocks 1) q are employed, at this.v point, .on each side .of the connection.

It will be observed'that the pipe I enters the vessel L at its top,'and emerges at 'its bottom, and enters the -vessel M at its bottom, emerging at its top, and, also,

that, -between the vessels,'and at either extremity of them, vit bends upward and over, in the form o'f an arch. rIhis construction is adopted in order to properly conduct the gas or vapor through the fluids in the-vessels, without allowing any 'communication of the uids from one vessel to another.

The operation of thevcombined a'pparatus,'vvhich I l have herein described, isi exceedingly perfect and effect# ive, manufaotiuing 'a very superior quality of gas, at a less expense than by any other machine, and enabling the operator, in fact, 'to4 produce gas of any quality desired.

In the practical operation of the apparatus, the gasoline or other hydrocarbon is introduced into the tank A, and a little iire is made orplaced in the vessel D,

suihcient to heat the coiled pip'e B over it. The cock b is then opened, or partially opened, and the gasoline permittedto iiow from the tank. In passing through the involutionsof 'the pipe, over the heated vessel, it

israpidly vaporzed, and, in the form of gas, enters the gasoi'neter E. As soon as the latter has been par- 4tially filled, the tire ,u ia'y be removedfror'n the Vessel D, or allowed to go out, 'and'the burnerF may be lighted, from which sufiicient h eat will be continuously supplied, to keep up the process as longas desired.

y After. the gason'ieter E has been thus supplied, the quality of `the gas may be tested by therbiirner K, and,

'it' foundto be poor, it may be improved by means of the vesseLL or M, while, if too rich, as will usually be the case, it may be dilntedwith air from the'l pump Q; 1t can thus be adjusted and controlled perfectly.

By meansof the air-pump Q and the vessels M and -L, the process may be partially reversed, if desired, and

the gasometer E filled through the pipe I. In this ca-se, the vessels M and L are to be partially lledwith gasoline, the cocks p and i"closed, and the air is to be forced from the air-pnmp`, through the gasoline, to the gasometer. The latter having been lled, the gas or carburet'ted air can be heated and xed by means of thecoiled pipe B and the lighted burner beneath it,

and then conducted 'away .to a suitable reservoir, for

use; or, after filling 'the gasometer, the cock p'may be aopened; and the. carburetted air allowed to passr back' through' the vessels L and M to the gasomete'r N,

as described abovefjlu this manner', the air will be doubly carburetted, once in passing` to the' reservoir VE, and once in passingback to the reservoir N. Ou its return passr ge, iffound to be too rich, it can be'diluted -by the pump Q, as' before'described.

Having thus desclibed my invention, 'What I claim as neng, and' desire to secure by Letters Patent, is

l. The'arrangement of the tank A, coiled o1' involuted i pipe B, gasometer E, burner F, vesselD, pipev I, vessels L and M, airpurnp Q, and gasometer N, when the 'said parts are provided with suitable cocks, and`constructed to operate in the manner and for the purpose indicated.
